Manufacturers of the Spiral Heat Exchanger.

The Spiral Heat Exchanger is an apparatus for transmitting heat in accordance with a completely new design, based on recuperative principle of heat transfer. It can be economically used for recovery of heat from practically all liquids, vapors, steam and gas mixtures, even in cases where such recovery heretofore has been considered unprofitable. In contrast with the conventional type of heat exchanger, the Spiral design consists of two concentrically rolled plates. Between the spiral plates are two narrow passages, through which the heat exchange mediums flow, either contra or cross-current. The ends of the spirals are kept tight by means of covers and are effectively sealed against any inter leakage of the mediums.
